OP6166 Methylammonium Iodide (CAS No. 14965-49-2)

Methylammonium Iodide Description

Methylammonium Iodide (FABr) is an organic salt with the chemical formula CH₃NH₃I. It consists of a methylammonium cation (CH₃NH₃⁺) and an iodide anion (I⁻). This compound is commonly used in the production of perovskite materials, particularly for perovskite solar cells and other optoelectronic devices.

Methylammonium Iodide Applications

• Perovskite Solar Cells: MAI is a key precursor in forming methylammonium lead iodide (CH₃NH₃PbI₃ or MAPbI₃), a perovskite material that is widely used as the light-absorbing layer in perovskite solar cells due to its excellent photovoltaic properties.
• Light-Emitting Diodes (LEDs): MAI is also used in the fabrication of perovskite-based LEDs (PeLEDs), which exhibit efficient light emission properties.
• Photodetectors and Lasers: MAI-based perovskites are used in various other optoelectronic devices, such as photodetectors and lasers, because of their tunable optical properties.

FAQs

Q1: How is Methylammonium Iodide used in solar cells?

Answer: MAI is a key precursor in the formation of methylammonium lead iodide (MAPbI₃), a perovskite material that is used as the active layer in perovskite solar cells. This layer absorbs sunlight and converts it into electricity, making MAI essential in the fabrication of high-efficiency photovoltaic devices.

Q2: How does Methylammonium Iodide compare to Formamidinium Iodide in perovskites?

Answer: MAI and formamidinium iodide (FAI) are both used in perovskites, but they form perovskite materials with different properties. MAPbI₃ perovskites (made with MAI) generally have a bandgap of around 1.55 eV and offer good initial efficiency, but they are less stable compared to FAPbI₃ perovskites (made with FAI), which have better thermal and moisture stability.

Q3: What are the common purity levels of Methylammonium Iodide?

Answer: MAI is typically available in high purities, ranging from 99% to 99.99%, depending on the intended application. High purity is crucial for ensuring the optimal performance of perovskite solar cells, as impurities can affect the efficiency and stability of the perovskite film.
